A device for injection of a two-phase mixture composed of fuel and carrier air into intake pipes associated with the individual cylinders of a multi-cylinder, mixture-compressing combustion engine, the device having carrier air apportioning means which apportions a carrier air current, branched off the intake manifold and conveyed by an air pump, to the injection lines associated separately with the individual cylinders of the combustion engine, a fuel injection valve is provided which injects the fuel by way of separate injection nozzles into the individual injection lines, the carrier air apportioning means is provided with a carrier air collecting space formed in a housing containing the injection valve, the collecting space surrounding the injection valve in annular manner and communicating, on the one hand, with the air pump and, on the other hand, with the injection lines, a carrier air reservoir is provided between the carrier air collecting space and the injection lines, which surrounds the injection valve in annular manner to ensure precise and uniform apportioning of carrier air to the individual cylinders, the carrier air reservoir cummunicating with the carrier air collecting space by means of a connecting line which is constricted in its cross section.
